For Irenaeus tradition included three things
1)the faith that was handed on-oral or in writing
‘For how should it be if the apostles themselves had not left us their writings? Would it not be necessary to follow the course of the tradition which they handed down to those whom they did commit the Churches?’
AH 3,4:1
2)a living authority
“Wherefore it is incumbent to obey the presbyters who are in the Church…those who, together with the succession of the episcopate, have recieved the certain gift of truth…”
AH 26:2
3)transmission and preservation by succession.
“In this order, and by this succession, the ecclesiastical tradition from the apostles, and the preaching of the truth, have come down to us. And this is MOST abundant proof that there is one and the same vivifying faith, which has been preserved in the Church from the Apostles until now, and handed in truth”
AH 3,3:3
“Then I have pointed out the truth, and shown the preaching of the Church, which the prophets proclaimed(as I have already demonstrated), but which Christ brought to perfection, and the apostles have handed down , from which the Church, recieving [these truths], and throughout all the world alone preserving them in their integrity, has transmitted them to her sons. Then also-having disposed of all questions which the heretics propose to us, and having explained the doctrine of the apostles, and clearly set forth many of those things which were said and done by the Lord in parables–I shall endeavor, in this fifth book of the entire work which treats of the exposure and refutation of knowledge falsely so called, to exhibit proofs from the rest of the Lord’s doctrine and apostolic epistles; [thus] complying with demand, as thou didst request of me(since indeed I have been assigned a place in ministry of the word); and, labouring by every means…and convert them to the Church of God…that they may preserve stedfast the faith which they have recieved, guarded by the Church in its integrity, in order that they be in no way preverted by those who endeavor to teach them false doctrine…”
AH V Preface
“Now all these [heretics] are of much later date than the bishops to whom the apostles committed to the Churches; which fact I have in the third book taken all pains to demonstrate. It follows, then, as a matter of course, that these aforementioned, since they are blind to the truth,and deviate from the
way, will walk in various roads; and therefore the footsteps of their doctrine are scattered here and there without agreement or connection. But the path of those belonging to the Church circumscribes the whole world, as possessing the sure tradition of the Apostles, and gives unto us to see that the faith of all is one and the same …And undoubtily the preaching of the Church is true and stedfast, in which one and the same way of salvation is shown throughtout the whole world…For the Church preaches the truth everywhere…”
AH V 20,1
“Those, therefore, who desert the preaching of the Church, call in question the knowledge of the holy presbyters…It behoves us, therefore, to avoid their doctrines, and take careful heed lest we suffer any injury from them; but to flee to the Church, and be brought up in her bosom, and be nourished with the Lord’s Scriptures.”
AH V 20,2
Episcopal Succession
“Wherefore it is incumbent to obey the presbyters who are in the Church, those who as I have shown, possess succession from the apostles; those who, together with the succession of bishops, have recieved the CERTAIN GIFT of TRUTH, according to the good pleasure of the Father. But [it is also uncumbent] to hold in SUSPICION others who DEPART from the primitive succession of the succession, and assemble themselves…But those who cleave asunder, and separate the unity of the Church, [shall] recieve from God the same punishments as Jeroboam did”
AH 4,26:2
